This detailed educational wall chart provides a comprehensive look at the anatomy and classification of the earthworm, making it an ideal poster for biology classrooms, laboratories, and student study spaces. It is designed to simplify complex biological structures through clear illustrations and well organised labelling.

The main section of the poster focuses on the anatomy of an earthworm, featuring a large, detailed diagram that highlights both external and internal structures. Key features such as segments, clitellum, mouth, anus, and bristles are clearly labelled, along with internal organs including the pharynx, oesophagus, crop, gizzard, intestine, and reproductive structures. The chart also shows important systems like the dorsal and ventral blood vessels, nerve cord, and muscular hearts, helping learners understand how the earthworm functions as a complete organism.

Additional educational value is provided through classification details, where the earthworm is placed within the phylum Annelida and class Oligochaeta. This helps learners connect anatomical knowledge with broader biological taxonomy.

The lower section of the poster introduces the diversity of segmented worm classes, including Polychaeta and Hirudinea, with visual examples such as marine worms and medicinal leeches. This comparison expands understanding beyond the earthworm and provides useful context for studying invertebrates.

This high quality poster is perfect for reinforcing key biology concepts, offering a clear and engaging visual reference that supports both teaching and revision.

Our wallcharts are engineered for durability and educational impact, designed to withstand the rigors of both classroom and home environments.
